Anacrusis in Music Theory
Anacrusis, derived from the Greek word meaning "to push up," refers to one or more unstressed notes that precede the first strong beat of a musical phrase. It often serves as an introduction, setting the rhythmic and melodic context for what follows. Anacrusis is significant in various music genres, including classical, jazz, and contemporary styles, as it adds dynamic interest and can enhance emotional expression.
